Abstract

A method and device for thickening mass or suspension by means of one rotating disk filter immersed in the mass or suspension where overpressure is applied to the outside of the plates' filter surface. Overpressure air is also used during filtration to loosen filtered mass from the plates' filter surface by directing overpressure air to a sector for each plate to be loosened. From there the air penetrates through the filter surface to the filter surface's outside. The disk filter is equipped with a vessel 1, a cover 7 above the vessel and sectors 3 arranged on the axis 5 forming rotating filter disks 4 in the vessel. In order to effect the overpressure outside the disks' 4 filter surface, the longitudinal cavity 14 or 19 inside the axis 5 is connected with the overpressure source 15 and the disk sector 3 which is located at the loosening place of each respective disk. <IMAGE>
